A completely different alternative from the suggestions you received so
far is to pass an output iterator to your function so that its users
are free to choose the container in which they want your characters.
Something like

template <typename OutIter> void f(OutIter oi)
{
  while (thereAreMoreChars())
    *oi++ = nextChar();
}

Cheers,

Hi!

That's the C++-way I'd prefer. It avoids any memory allocation 
issues present in previous examples.
